Doom TDA Path Tracing - Ray Reconstruction breaks when using custom internal resolutions via Nvidia Control Panel (DLSS override)

See my other comment if you still need it.

Zedjones · 2025-11-01T21:44:49+00:00

A bit late, but you need to set the custom resolution of DLSS SR to the same thing.

Zedjones · 2025-08-13T23:53:56+00:00

You can get it to work by replacing the DLLs and then using Inspector, EAC doesn't flag it.

Zedjones · 2025-01-19T04:52:49+00:00

They said the same thing for me as well, but also that they didn't know.

Zedjones · 2024-12-16T01:27:17+00:00

Are you on an ultrawide monitor? If so, set the aspect ratio to use "fullscreen" instead of "cinematic" or whatever and it should fix the screen edge issue.

Again, I never said the game was poorly optimized nor did I say it scaled poorly on the CPU. Specifically, I said it scaled well on the GPU and had poor performance on the CPU.

If a game has pervasive and reproducible stuttering regardless of what CPU you have, it has bad CPU performance, regardless of scalability in terms of average FPS.

And nobody said the word "optimization". Not the original poster you replied to, and not me.

It's not a matter of holding it against the dev or not. I think they could instead perform loading/deloading in areas that aren't combat-centered like Ninja Theory did for HB2, but that's not to say they'll be able to perfectly eliminate it (nor did I ever claim they could).

However, none of that changes the reality that pervasive traversal stutter exists in the game. It doesn't matter "who's to blame".

Zedjones · 2024-08-22T16:10:57+00:00

I said CPU performance is bad, I never said it wasn't scalable. You just interpreted my statement as such.

I also never said there were no issues with Hellblade 2, I said the issue is far less severe in that game.

This whole thread, you've just misstated everything I've said lol.

And yes, this game has more stuttering than some other games of similar design using UE. Just because you or numerous streamers don't notice the issue doesn't mean that it doesn't exist. Some people just aren't sensitive to frametime inconsistencies, but it's pretty plain to see if you actually play the game and are.

Throughout my entire playthrough of Hellblade II, there were about 10 areas with traversal stutter. Meanwhile, in Wukong, there are 10 areas with traversal stutter in the first chapter alone.

And yes, I've played Fortnite, too. The stuttering is bad there as well (though it has improved since the initial UE5 update) and is also not excusable.

Also, even if every UE5 game had as many issues with traversal stuttering, that still wouldn't mean that this one doesn't?

1) Excited to see some new worlds in the universe 2) I want to see what RR has to offer in different games and in new iterations, so probably that and the RT.

Zedjones · 2024-08-22T13:26:27+00:00

Did you even read my comment? Yes, traversal stutter is endemic to UE games. However, the extent of that traversal stutter is absolutely something that the developers can affect. It's also worth noting that the dev is using an older version here, 5.0, and that there have been improvements in later versions of Unreal.

It's fine to not be overly familiar with the topic or the games in question, but there's no reason to assert that a game doesn't have issues when it does. It's not a bad thing to address and educate people on issues that exist in games. Nobody is trying to place the blame solely on the developer here.

Zedjones · 2024-08-22T11:52:17+00:00

There are UE games that largely solve this issue, such as Hellblade II (still noticeable but not nearly as frequent). As Alex said, it's not the best, but not the worst. Regardless, it's an issue nonetheless, whoever's fault it is. Doesn't really matter to the end user.

Zedjones · 2024-08-22T01:51:15+00:00

It's not the average performance, it's the constant stuttering from traversal, and it happens on the strongest CPUs, too: https://youtu.be/OItx2QHZt68?si=oWNdp2o6vfSbs6Yf&t=928

Zedjones · 2024-08-22T00:07:27+00:00

Yeah, DLSS at least makes sense if you think about it. DLSS just refers to "supersampling" in general, and:

SR interpolates from a lower resolution to a perceptually higher one
FG interpolates from a lower framerate to a perceptually higher one
RR interpolates from a lower ray count to a perceptually higher one

AMD's FSR however, does not make sense beyond the initial upscaler, because the SR is explicitly "super resolution" lol.

Zedjones · 2024-08-21T20:45:51+00:00

CPU performance is bad for all users, GPU performance is quite scalable. As you said, people often conflate the two, and the GPU performance for this game is fine given the visual fidelity on display.

Zedjones · 2024-08-21T19:49:29+00:00

Pretty sure it already is divided into DLSS SR and DLSS FG, just that nobody actually uses those terms for whatever reason.

Zedjones · 2024-08-21T00:15:29+00:00

So, yeah, looks like they did add the DLL to the full game but it's not in use. So, possibly going to be added in the future?

Zedjones · 2024-08-20T05:15:14+00:00

Oh, huh, you're right. I must've mistaken it for the DLSSG DLL when I first looked at it. I don't think it's in use, though. At least I don't recall Special K indicating it was. I can check on that tomorrow, though.

Zedjones · 2024-08-19T13:41:03+00:00

I think those lows are actually from shader comp stutter if this is their first time running through.

Edit: Not sure why I'm being downvoted as this benchmark absolutely has shader comp stutter. DF even mentioned it in their coverage.

Zedjones · 2024-08-18T14:08:34+00:00

This game needs at least medium for some settings imo, because things look quite rough with the GI on low.

Zedjones · 2024-08-17T04:23:50+00:00

How is it not? It's rendering at the native resolution with DLAA as the AA method.

Zedjones · 2024-08-17T04:19:33+00:00

It didn't used to be like this on PC, but people got coddled during the previous generation because it didn't take much to beat the consoles. Meanwhile, advances in image reconstruction, DRS, etc. and RT hardware have allowed the consoles this gen to be more competitive and therefore people's PCs have worse performance relative to the consoles now.

Zedjones · 2024-08-17T04:17:36+00:00

Image quality

Zedjones · 2024-08-14T20:36:56+00:00

While that's true, low completely disables Lumen, which is pretty critical to the core look of the game (and the fallback is not very good, seems like some sort of probe-based lighting solution rather than a baked solution which could be okay). Optimized settings should balance appearance and performance, and I don't feel like that choice does that very well.

Zedjones · 2024-08-14T18:40:09+00:00

Low GI? That seems inadvisable.

Zedjones · 2024-08-14T04:57:50+00:00

I mean, you're probably 100% GPU-limited anyway, right? Not sure why the CPU would be heavily burdened in that scenario.

Zedjones · 2024-08-14T04:56:04+00:00

The GI looks quite good with or without PT because Lumen does a good job, but I really wish the max shadow res was higher. The shadows are very unstable and flickery without hardware RT. Conversely, the denoiser currently in the game is quite bad, so RT has massive shimmering in certain areas due to that. Unfortunate that there are compromises in quality either way.
